It's not just advancing the current message, it's keeping the previous ones. Currently, your plugin always clears the box before typing the new message in.
Ideally, what I'm looking for is having several static windows that can be revisited when opened and closed. I can already do that with your plugin, as the current message stays in the window when I close and reopen it, but what I am looking for now is the ability for those static windows to keep every line previously added as new ones appear, like in an old-fashioned computer terminal.
You mentioned a text code workaround, is it capable of this? Or were you thinking of something else?
Thank you for your time, by the way.
